I am in great admiration of these extraordinary heroes who ride the 180-mile Pan-Mass Challenge through all kinds of weather over a two-day period to raise money in support of fighting cancer. Some are cancer survivors themselves and others ride for family, friends and/or humanity. They all seem to be enjoying their efforts, despite the toll it must take on their bodies. I've supported a friend who has participated for the past 10 years, and my former employer continues to match my contributions. It's a great event to watch and photograph.
